Lowest street price from a reputable dealer in Germany is 620€ (incl. 19% you-know-VAT).
And no, those are not borrowed lenses: I have to pay for them upfront, but German laws on Intenet sales impose a 14 day period where you can give the gear back.

When ordering lenses or other items in the EU (distance selling) then the distance selling directive applies. This gives you the right to cancel the order for a short time after you received the item and inspected it. The UK implementation explicitly states the seller can not put barriers to that inspection, such as requiring items to be unopened/unused. Big sellers like Amazon are generally good with it. I've heard that some small places don't understand the requirements and can involve court action to get things sorted. As always, if you intend to make use of it do check out the details first.

It "saved" me from the disappointing new Tamron 28-300 I got previously as it was worse than my old one.

Taxes wise, you pay the VAT of the selling country, usually included in price already.

I've transferred the following Sigma 70-200 related posts by Christian-NRW from the Tamron 70-200/2.8-thread here to give a something to mull over while I'm waiting for my copy of that lens:--------------------
To get an impression what kind of dreamy effect the sigma delivers in the near field, I've uploaded a 50% size sample shot from photokina - its clearly visible, even more so at 1:1 100%. This JPG ist OOC, shot was taken around the max. mag. distance of that lens.

If you increase the distance, the glowness is reduced and remains visible mostly around highlights. Nevertheless, it's still there even in the shadows, visible by the overall reduced contrast:

In the far field, the picture looked ok, but lacked the punch that those of the tamron had. There mighht be a small backfocus on this lens as I aimed for the wheel and the brakedisc seems sharper, but overall I wasn't just impressed with the results I got (org. full size file):

Build quality was better at the sigma in terms of surface feeling, it just felt "metal". But as I know how fast this EX finish collects dust and dirt and just gets splotched, I'm not very keen on this finish. However, having a metal outer shell does indeed suggest some kind of reliability.

Here's the Sigma 70mm, notice the plane of focus is on the windscreen wipers although I clearly aimed for the wheels.

Update:
After looking again at Christian's images and the other reports about this lens plus assuming that the Sigma people had a perfectly QCed copy of their lens at the fair I finally killed the order.
I don't want to waste my and your time with products that have little chance to be a keeper. So, sorry 0eyvind, no review of this lens from me here

Sorry, forgot to mark this thread as well for email notification, so it slipped through.

I'm not sure what to think about the performance of the sigma. But the fact that there is no serious review out there that does not describe a somehow serious flaw makes me lack the enthusiasm to find an explaination. Because even if I would find one, I doubt it would solve the problems. It's sad because I really wanted it to be good. I'm a huge fan of sonic wave motors and wouldn't have hesitated to buy it. But there does not seem to be convincing proof despite those peoples who have bought one and have waited to long to send it back and now are showing 1024th sized images while crying out loud "thats sharp, sharp enough for me" (excuse my sarcasm).

And i can't seem to see what you mean. Whether you're negative or positive about the lens.

So - do you write/think negative or positive about the lens?
Because i really want this lens, and i'm getting reeally confused now. I would'nt be able to afford the Sony one, nor to send the Sigma one in 5 times or so. (50 usd each way ._.)

In your opinion, would it be worth getting it? Or does it has some real flaws. Because i god confused now

Sorry for not being clear (enough), 0eyvind!
Look at this image from Christian: http://www.abload.de/img/50p_dscf0033shs.jpgSee the white halo around the numbers on the focus ring? They have a "halo". And although the hair in front of the lens is quite sharp this effect of "blooming"/"halo" will seriously deteriorate the contrast in your images.
I've seen this in the Sigma 120-400mm also and didn't like it. It is hard to correct because the contrast degradation is only around bright colors, so you cannot just push up the contrast for the complete image.
Plus Christian is reporting focus-probs and I've really had enough of back-/front-focus on the Tamron 70-200/2.8 (which I will give back).

I will not buy a f/2.8 lens that I'm afraid to use at f/2.8. And as I already own a 150/2.8 macro and a 105/2.8 VR which have excellent IQ even fully open, I've not much to gain from a non stabilized, limited macro, limit IQ 70-200/2.8. Perhaps I should better get the Nikon 70-300 VR?!

If you have not covered some of the range already with a kit-lens or a prime I'd rather tend to suggest the Tamron 70-200/2.8 which either stopped down or with a little MF help can produce very good pictures.
